Be it knowmthat I, VVILLIAM A. Brains, a citizen of the United States, and a rcs1- dent of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and use :t'ul Improvement in Typograph Mechanism, of which the followmg 1s aspecifica- .tion, the principle of the invention belng herein explained and thebest modein which I have contemplated applying that princr ple, so as to distinguish it from other inventiors.

The present invention more specifically consists in certain improvements in typograph mechanism of the kind shown and described in my eo-pending application filed June 'lQ, 1915, Serial No. 35,070. The object of such present improvements 1s to adapt such'typograph mechan sm for the casting of slugs or type bars having a length less than the length of the casting slot in the mold; indeed, it is possible withthe arrangement of parts presently to be described, to cast individual type, or sorts, in any desired quantity, and with considerable rapidity. This is particularly advantageous, for the provision of an adequate stock of individual type of large sized characters thus rendered possible for even a small printing shop. To the accomphshment of the foregoing and related ends,.

said invention, then, consists of the means hereinafter fully described and particularly pointed out in the clanns.

The annexed drawing and the following description set forth indetail certain mechanism embodying the invention, such d1sclosed means constituting, however, but one of various mechanical. forms in which the principle of the invention may be used.

in said annexed drawing Figure 1 a plan view of a broken por tion '01 a typograph machine showing the parts of present interest; Fig. 2 is a transverse cross-section of the same on the line 2.?., Fig. 1; Fig, 3 iii a similar section on the line 3 3, Fig. 1; lg. 4 is a perspective view of one of the regular matrix used in the machine; Fig. 5 is a perspective view of a matrix bar of special construction, which forms one of the characteristic features of the invention; and Figs. 6 and :7

are perspective views of a short type bar, "and of an individual type forme with my improved mechanism.

Specification pf Letters Patent. P w t 715 1917 Application filed August 20, 1915. Serial No. 16,499. i

Of the casting mechanism proper, the

only parts of present interest, or'nppeaping 1 of the mold just described, and including suitable means, (not shown) whereby the molten metal may be forced into the cast- .,.ing slot 3 in the mold, when the latter is in proper positloinas will be readily under stood. Thefenll of'the nozzle is prox'idcd with a perforated plate d, of usual construction, which comes into direct contact with the underside of the mold, the slotin the latter being of such fdrm and dimensions as to serve as a mold for a. slug body or type bar of the desired length and width.

In its casting position, the mold registers With, or rather liesin, an opening 5, in ahorizontally extending top 6 of the general machine frame, so as to be substantially flush with the upper surface of such top, or rather with the surface of a. troughdike depression 7, that extends transversely across the same. Associated with the mold,

so as to be carried therewith in its vertical;

movement, is a trimming knife, or blade'ilfi' Such matrix holder is in the to receive and hold a number otdetached matrix bars 11 (see Fig. 4) in selected relation, as shown in Fig. l, thereby forming a composite matrix apart from, but adapte to coiiperate With said casting mechanism 3.1:

Disposed alongside the trough or depres sion 7 in the top designed to rece ve succes 'sive matrix holders, as just set forth, is a lateral stop 12, that lies parallel with one side of the opening 5, wherewith the mold registers in its casting position. Beyond such stop 12 is a terminal stop-block 13th at projects over the trough 7 so as to engage the rear end of a-holder' 10 when the latter 15 disposed alongside such lateral stop 12; while adj acent the opposite side of the open: ing from such lateral stop, is a presser foot 14, adapted to force a holder closely against such stop 1'2. Finally, a vertically movable bar 15 (showl'rin Figs. 2 and 3), preferably having its lower edge rounded, is adapted to be brought down and vertically clamped on top of the bodyjot' matrices in the holder,

when this located and laterally clau i'ped. v The holder 10, in the structural form illustrated, comprises two end pieces se-' cured to side n'iembers oi suilicient length to provide a rectangular opening somewhat larger than the maximum length of the slug which it is desired to cast. Slidably mounted between the slde membersis a block, or clamp. member 16 that is engaged by the threaded portion of a'screw '17, rotat/ably "smau'ed in the adjacent endpicce, and provided with a knurled head, by rotation of which, said block can obviously be advanced or retracted to clamp the assein Wbled matrix bars 11 or matricesas they are termed iu the shop.-

llu-se bars are of the trated in Fig. 4, being, in ell'ect, plates or bloeks'of uniform height, but of varying width, to accommodate character impres sions IH ol' correspoiulingly varying width. The latter are struck, or driven in the l ottoms of recesses 19 cut in whatanay be called the lower edges oi the bars, tl'iese recesses having in general, the dimensions which it is desired the head of the slug should-have. The upper portions of the matrices projectlaterally in the form of cars 20, which are adapted to rest on the side pieces of the holder 10, leaving the hodies of. th matrices depend between, and some'distancc below such side pieces, as shown in Fig, 3. it wilLbe umlerstoodtliat where a blank, instead of a character, is desired in the slug to be cast, a matrix bar will be inserted, either with, or without a recess in its under 'l'acc. but with no character inipress-ions, so that the correiaionding portion of the face oi the slug will make no llll]')l.b'- sion when set up in the printing press form.

In addition to such regular matrix bars,

or matrices. including in this term both those with character impressions and those without, ,lprovide in the present instance, what may be termed cut-oil bars 21, of the form; clearly illustrated. in Figs. 2 and 5. In other words, such special matrices, in-

general form illusstead ofihaving recesses i .lnfiklf under faces, and carrying character impresslons, are, an

the contrary, provided. with depending proat any point in an assembled body the regular matrices,-the' slug cast from such assembled body Will be interrupted, or in other words, out in two at the point ofinsertion'of the projection i22into the mold These bars 21 have otherwise slot. Obviously also, as many such cut ofl' bars may be inserted in a line as desired, so as to cut up the slug into a series of short slugs, comprising for example single words, or even individual type, as illustrated in lligs.-'(3 and '1, respectively. i f

The manner in which the foregoing mechanism, including my'improved cut-oil bar is utilized in ractice, has, it is belieyed, been already suihciently explained, since the gen eralcasting operation as well as the trimming of the bottom of the slug after it has been cast, form no part of the present invention. :In all kinds of I isplay Work and advertising matter, it ls-constantly necessary to em-poy slugs, or type-bars, that are,

shorter than standard column widtlnas, for example, to fill in beside cuts and inserts.

.W ith the ordinary lllergenthaler equipment,

the only way to obtain'such short slugs is either to adjust the mold, which obviously is feasible only where a large number of the short-length product is required, or tosaw in two a regular slug, which is the common expedient, but an unsatisfactory one, because the interior of the slug body, as is well known,

is always more or less hollow or spongy, on] y the outside shell being continuous and solid. Accordingly, when the slugds out across, the cut'end will not stand up in the form but tends to collapse, frequently causing serious trouble; Moreover, the'cut ends,

are always more or less rough, thus making fitting diiiicult.

All the foregoing objections are obviated by my presentimproved mechanism'and method oi casting short slugs, so that not only may the latter be made as expeditiously as the regular size, without bothering tochange or adjust the mold, but the bodies ort such short slugs. are as complete and .solid as those of regular size.

Other modes of applying the principle of my invention. may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, pro vided the means stated by anyof the followv its oppositely extending lateral projections,said

member being formed with an elongated opening adapted to receive and support a number of said bars in selected relation with such pro1ect1ons'restmg on the sldes of sald member, so as to form a composite matrix, the mold cooperative edges of said bars lyring below the under face of said member when thus supported therein; and other bars provided with similar'lateral projections, and with otheaprojections' on their mold cooperative edges adapted to extend from such composite matrix into the mold,
